Forms Authentication Bug

[davejuk]

I'm using forms authentication under .NET 2.0 to restrict access to a folder.

The problem I have is that some IE users are taken to the default page once they enter a valid username/pass, but then they get a JavaScript error in the bottom left of their browser and are unable to get past this page. They just get taken back to the login page. I believe this is only affecting IE6 users but I have been unable to reproduce. Is this a known issue with forms authentication, or do they have cookies or something disabled?

The relevant section from my web.config can be seen below:

..
 
<authentication mode="Forms">
      <forms name="wwauth" 
      loginUrl="/members/Login.aspx" 
      defaultUrl="/members/" 
      protection="All" 
      timeout="30" 
      path="/" />
    </authentication>
 
    <authorization>
      <allow users="*" />
    </authorization>
 
  </system.web>
 
  <location path="members">
    <system.web>
      <authorization>
        <deny users="?" />
      </authorization>
    </system.web>
  </location>
 
..

Have you tracked down the javascript error? (ProTip: use the ie developer toolbar.)

I haven't been able to reproduce it, so it's a little awkward to get a customer to do it!

Why not? There is the IE6 Virtual PC for testing exactly this sort of thing . . .
